The accepted answer is D. A data structure that allows insertion and removal of elements from both the front and the back.. In computer science Dequeue refers to which of the following is answered by A data structure that allows insertion and removal of elements from both the front and the back option D Option A A self-balancing tree data structure that maintains sorted data and allows searches insertions and deletions in logarithmic time commonly used in databases does not match the stem it is a near-miss used to catch incomplete recall of A data structure that allows insertion and removal of elements from both the front and the back Option B A matrix in which most of the elements are zero often stored using specialized structures to save memory does not match the stem it is a near-miss used to catch.

A. A self-balancing tree data structure that maintains sorted data and allows searches, insertions, and deletions in logarithmic time, commonly used in databases.
